DeGast Piste Diamant Silk

Cycling track tyre for six-day event. 
The silk fibre will give you extra comfort
The diamond tread provides excellent 
grip on both wooden and concrete tracks. 
To reduce rolling resistance, the sidewalls 
do not have a protective layer 
(we recommend using wheel bags during transport to protect the 
sidewalls). The diamond tread provides excellent grip on both
wooden and concrete tracks.
